SHEET-METAL CAN.

SPECIFICATION forming part of Letters Patent No. 269,814, dated December 26, 1882,

' ApplicationfiledJune22,1882. (N model.)

' the can or box, and form a continuous tubular rim around the upper edge thereof. lleretofore the ends of the tube formed on each side piece have been united, so as to abut against the ends of the tubes on the adjacent pieces. In this construction it is difficult to solder the ends of the tubes firmly together without loading or accumulating the solder over the joints to. a considerable thickness, thereby involving considerable expense forsolder and giving the joints a somewhat bungling appearance.

My invention has for its object to provide an improved construction whereby the ends of the tubes can be more firmly and neatly united than heretofore, and by'the use of a smaller quantity of solder.

' To this end my invention consists in the improvements, which I will now proceed .to describe and claim.

0f the accompanying drawings, forming a part of this specification, Figure 1 represents atop view of a rectangular can or box cmbodying my improvements. Fig. 2 represents a vertical section ou-line 00 00, Figs. 1 and 3. Fig. 3 represents a horizontal section on line y 3 Fig. 2, looking toward the top of the can. Fig. 4 represents a perspective view of a part of one of the sides of the can. sents a top view of the same. Fig. 6 represents a vertical section on line 2 2, Fig. 1. Figs. 7 and 8 represent respectively views of portions of the blanks from which the sides shown in Figs. 4 and 6 are made.

The same letters of reference indicate the same parts in all the figures.

In the drawings, A represents a rectangular can or box, the walls of which are formed of four side pieces, B B 0 O, of sheet metal, each of which is rolled inwardly at its upper edge to form a hollow tube, D; but this feature of itselfforms no part of my invention.

Fig. 5 repre-.

.In, carrying out my invention I form the blanks from which the. sides B B are made in such manner that the ends of the tubes .D formed on said sides will be adapted to re- 0Pi\6 the ends of the tubes formed on the sides 0 O, or, in other words, will partially overlap the upper and lower surfaces of the tubes formed on the sides 0 0, said overlapping surfaces being capable of being strongly united by a comparatively small amount of solder. To this end I provide the sides B with tongues F, which are arranged to'nroject under the tubes formed on the sidesU O, as clearly shown in Figs. 2 and 3; I also formtbe sides 13 so that the ends of the tubes on the sides U can extend partially under the upper surfaces of the tubes on the sides B and abut against the sides B, as shown in Fig. 6, the ends of the tubes on the sides 0 being curved, so as to fit the curvature of the sides B. The described features will be secured by giving the blanks from which they are made the form shown in Figs. 7 and S, which I prefer to do by means of suitable dies. I have found that by the described construction great strength can be obtained at the corners of the can by the employment of about one-third of the amount of solder required by the construction formerly adopted.

1 do not limit myself to the precise outline for the blanks shown in Figs. 7 and 8, as the same may be variously modified without departing from the spirit of my invention.

1. In a rectangular sheet-metal can 'or'box having the sides rolled inwardly to form a tubular rim, the tubes on the sides B Bformed to overlap the tubes on the sides 0 0, substantially as and for the purpose set, forth.

2. The combination of the sides B B and (J U,-the tubes of the sides B-B being made to overlap the tubes of the sides (J G, and the tubes of the sides 0 U being made to abut against the sides B B, as set forth.

In testimony whereof lh'ave signed my name to this specification,in-the presence of two subscribing witnesses, this 19th day ofJune, 1882.
